Mmm. Yeah, I think an alternative to SIOCGIFCONF might be the thing.
getifaddrs is pretty nice, and it has the additional advantage that it can
support IPv6, which SIOCGIFCONF does not. I'm not certain whether it
returns "down" interfaces or not, but we can hope so. Unfortunately it's
not universally available; when I wrote this code at least, it wasn't
around on Debian, though that's since changed. So a configure check and
an ifdef would probably be in order.

You're correct, this is a Wine bug.

I prefer it in fact.
